Super Humans - Charles Louis Fefferman

Charles Louis Fefferman (born April 18, 1949) is an American mathematician at Princeton University. His primary field of research is mathematical analysis. A child prodigy, Fefferman entered college by the age of eleven and had written his first scientific paper by the age of 15 in German. After receiving his bachelor's degrees in physics and mathematics at the age of 17 from the University of Maryland and a PhD in mathematics at 20 from Princeton University under Elias Stein, Fefferman achieved a full professorship at the University of Chicago at the age of 22. This made him the youngest full professor ever appointed in the United States. At 24, he returned to Princeton to assume a full professorship there — a position he still holds. He won the Alan T. Waterman Award in 1976 (the first person to get the award) and the Fields Medal in 1978 for his work in mathematical analysis. He was elected to the National Academy of Sciences in 1979. He was appointed the Herbert Jones Professor at Princeton in 1984. In addition to the above, his honors include the Salem Prize, the Bôcher Memorial Prize, and the Bergman Prize, as well as election to the American Academy of Arts and Sciences. Fefferman contributed several innovations that revised the study of multidimensional complex analysis by finding fruitful generalisations of classical low-dimensional results. Fefferman's work on partial differential equations, Fourier analysis, in particular convergence, multipliers, divergence, singular integrals and Hardy spaces earned him a Fields Medal at the International Congress of Mathematicians at Helsinki in 1978. His early work included a study of the asymptotics of the Bergman kernel off the boundaries of pseudoconvex domains in \mathbb C^n. He has studied mathematical physics, harmonic analysis, fluid dynamics, neural networks, geometry, mathematical finance and spectral analysis, amongst others.

Charles Fefferman and his wife Julie have two daughters, Nina and Lainie. Lainie Fefferman is a composer, taught math at Saint Ann's School (New York City) and holds a degree in music from Yale University as well as a Ph.D. in music composition from Princeton. She has an interest in Middle Eastern music.[ Nina is a computational biologist whose research is concerned with the application of mathematical models to complex biological systems. Charles Fefferman's brother, Robert Fefferman, is also an accomplished mathematician and former Dean of the Physical Sciences Division at the University of Chicago. Fefferman has published several articles. His most cited papers include, in the order of citations:
